Conversion Functions VB.NET

Visual Basic supports a number of ways of converting from one type to another. The conversion function would take such a value , String, expression and attempt to convert it. It the conversion 
is successful , the function would return an appropriate value.

1. CBool :- CBool Stands for Convert to Bool . It converts String , Charcter or numeric expression into boolean value .

Synatax :- CBool ( expression )

Example :-

Dim a, b As Integer
        a = 10
        b = 20
        Dim check As Boolean
        check = CBool(a > b)
        MsgBox(check)

2. CByte :- CByte stands for Convert to Byte Data Type. It converts numeric or floating values to byte Data Type.. If fractional part is given in variable-name then it will round off it to integer type.

Synatax :- CByte ( variable-name )

Example :-

Dim num1 as Double
Dim num2 as Byte
num1 = 2144.7865789
num2 = VByte( num1 )
Msgbox ( num2 )


3. CDate :- CDate Stands for Convert to Date type. It converts any valid form date format given as argument to it into Date

Syntax :- CDate ( Sting_Variable_Name )

Example :- 


Dim DateString As String 
Dim Finl_Date As Date
DateString = "July 3, 2013"
'The following line converts date format given in Date Type and give
it to Finl_Date

Finl_Date = CDate ( aDateString )

Msgbox ( Finl_Date.tostring())


4. CDbl :- CDbl stands for Convert to Double Data-Type. It converts 
the any given integer value to Double floating value


5. CInt :- CInt Stands for Convert to Integer Date -Type . CInt is 
widely used when converting from numbers or integers entered in string variable to convert it into integers to perform any Arithmetic operations.


Syntax :- 
CInt ( String_Variable )






Example :- 
Dim Var As String = "10"
Dim num1, num2 As Integer
num1 = CInt(Var)
num2 = 10
MsgBox(num1 + num2) 
 
 'It Returns 20









6. CChar :- CChar Stands for Convert to character. It Takes a String 
Variable as input Argument and as it convert it into char so it passes

the first character of specified string varible to a character variable



Syntax :-
CChar ( String_Variable )

Example :-
Dim String_variable As String = "bvf" 
Dim char_variable As Char
char_variable = CChar(String_variable)
MsgBox ( char_variable )

7. Cstr :- Cstr stands for convert to string . It converts any  
integer floating value given as input to CStr into string type value

Syntax :-
Cstr ( Variable_Name )

 
Example :-
Dim Str as String
Dim input as integer
input = 12267.9999
Str = Cstr ( input )
Msgbox ( Str ) 
' It Returns 12267.9999 




8. CUInt :- It converts given data value into CUint datatype . Here, 
UInt stands for Unsigned integer type.

Dim Double_Variable As Double 
Dim aUInt_Variable As UInteger
Double_Variable = 39.501
aUInt_Variable = CUInt(Double_Variable)

Msgbox ( aUInt_Variable )

'It Return 40

9. CShort :- It converts the given data value into short integer type
data value.

Syntax :- 
CShort ( Byte_Variable )

Example :-
Dim Byte_Variable As Byte 
Dim Short_Variable As Short
Byte_Variable = 100
Short_Variable = CShort(Byte_Variable)
Msgbox ( Short_Variable )

10. CDec :- It converts the given data value into Decimal Data-Type value.



Syntax :-

CDec ( Variable_Name ) 
 
 
  Example :-
 
Dim Double_Variable As Double 
Dim Decimal_Variable As Decimal 
Double_Variable = 10000000.0587 
Decimal_Variable = CDec(Double_Variable) 
Msgbox ( Decinal_Variable )
